Topband: NCJ Ground Radial Article

Bob,
    I found the NCJ article (http://www.ncjweb.com/k3lcmaxgainradials.pdf)
most interesting - thank you.  I wonder if there is also an affect on the
angle of radiation with ground radial numbers.   Is the issue solely one of
gain and feed point impedance?

    At the moment I am helping a friend with his radials for a SteppIR
vertical to be used on 80 though 6 so some compromises or overkill will be
occurring here depending on the band.   I also use a SteppIR for 80, 40 and
30 (120+ ground radials 40 to 60 feet long average length 55 feet) with an
inverted L for TB using sixteen raised radials (12 to 16 feet) over the
SteppIR radial system which I think serves as the ground screen mentioned in
ON4UN's book.

   This is an interesting topic and one which does not die.   There are
always those of us coming up who need to learn from our more experienced
fellows.   Thanks to all.
